See the art of engineering at work when an older system for ringing church bells needed a makeover.
Implementing a custom security system for your home can be intimidating — unless you have the right software. This article guides you through the basic principles so you can design exactly what will work for you.
A glass mirror gives an exact copy of an image but with left and right swapped. A voltage mirror gives a copy of the input voltage but with the polarity swapped.
This device is a wonderful demonstration of clean, green solar power and is based on BEAM technology. It was inspired by the Magbot pendulum project in Dave Hrynkiw’s book titled, Junkbots, Bugbots & Bots On Wheels - which you can buy in the Nuts & Volts Web store!
This device will detect and report several common failures with household systems, so you can deal with them while they are still easy to fix. It's inexpensive ($60 or less, depending on your parts collection), easy to build, and doesn't require any contracts with monitoring services.

M2M —Machine-to-Machine Communications
M2M is essentially automatic communications between two “things.” An example is a vending machine sending data to a remote computer indicating that it needs refilling and the money box needs emptying.
